Inquiry (采购产品): Flexible drive shaft I am trying to add some wiring in my home walls and need a flexible drill bit extender that would go inside an 8' wall and drill a hole in top plate. The shaft on one end would attach to electric drill and accomodate a drill bit, say 3/8" on other end. Do you make such a tool and where can I buy or get a cataloge? **** Hidden Message ***** Bob Elliott 40513 Company: Home E-mail: b.elliott1@insightbb.com **** Hidden Message ***** b.elliott1@insightbb.com
